OK, so I have 2 day old puppies and they have fleas from the mom. I was wondering how I treat them? Do I use dawn?

At two days old they're way too young for traditional flea treatments.

Take a warm wet cloth, and wipe them down. Make sure that you dry them thoroughly when you're done because at their age they can't maintain their body temperature.

The best suggestion would be to see the vet.

On top of other suggestions, you should treat the mother. You can bathe and comb the pups all you want, but they will just hop back on if the mother isn't treated.
You have to be careful what to use because a lot of flea products are NOT safe for nursing mothers. Revolution is one that is.

Such a huge fan of Revolution.
